Sequoia sempervirens

Sequoia sempervirens, common names coast redwood, coastal redwood, and California redwood, is the sole living species of the genus Sequoia in the cypress family Cupressaceae. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees, reaching up to 115.5 m in height and up to 8.9 meters in diameter. The coast redwood is known to have reached 115 m tall with a trunk diameter of 9 m. Sequoia sempervirens has a conical crown, with horizontal to slightly drooping branches. The bark can be very thick, up to 30 cm, and quite soft and fibrous, with a bright red-brown color when freshly exposed (hence the name redwood), weathering darker. The root system is composed of shallow, wide-spreading lateral roots.The leaves are variable, being 1.5–2.5 cm  long and flat on young trees and shaded lower branches in older trees. The leaves are scale-like, 5–10 mm long on shoots in full sun in the upper crown of older trees, with a full range of transition between the two extremes. They are dark green above and have two blue-white stomatal bands below. Leaf arrangement is spiral, but the larger shade leaves are twisted at the base to lie in a flat plane for maximum light capture. The species is monoecious, with pollen and seed cones on the same plant. The seed cones are ovoid, 1.5–3.5 cm long, with 15–25 spirally arranged scales; pollination is in late winter with maturation about 8–9 months after. Each cone scale bears three to seven seeds, each seed 3–4 mm long and 0.5 mm wide, with two wings 1 mm wide. The seeds are released when the cone scales dry out and open at maturity. The pollen cones are ovular and 4–6 mm long. Its genetic makeup is unusual among conifers, being a hexaploid (6n) and possibly allopolyploid (AAAABB). Both the mitochondrial and chloroplast genomes of the redwood are paternally inherited. Our tree was planted in 2013.
